THE GEM, originally designed and created for LS Nitrous engines, is a Patent Pending, simple Plug & Play module that allows the ignition timing to be adjusted for the users needs. Interrupts the Intake Air Temperature Signal back to the ECU when activated to adjust timing in the ECU’s tune. Simple tuning adjustments made to one timing table (Instructions included on this process) to pull as much timing as the user desires. OEM pigtails for ease of installation and a two wire hook-up, Activation & Ground, allows for an install in less than five minutes.
